Overview

What they do
Founded by serial entrepreneur Kustaa Poutiainen, Stephen Industries operated as an industrial holding company for its first 30 years. Following the sale of Picosun to Applied Materials in June 2022, Stephen Industries transformed into a well-capitalised, ambitious family office and investment firm. Positioned as a flexible, evergreen investor, the firm is distinctive for its lack of fixed holding periods and its deep operational expertise in scaling industrial technologies and navigating medical device regulations. They enjoy a strong reputation in the Nordic ecosystem as a founder-friendly, ESG-driven partner capable of funding companies from pre-seed all the way to IPO.

Stephen Industries funds companies creating innovative HealthTech, DeepTech, and GreenTech solutions for a better world. Their vision is to drive long-term growth for high-potential companies that share their strict ESG (Environmental, Social, and Governance) values. They look for paradigm-changing innovations, transparent and honest company cultures, and strong ESG alignment. They favour companies with the potential to become global success stories, particularly those with Finnish or Nordic roots that they can help scale internationally without selling out too early.
